Yes. They are, I think, standard Fortran 77 functions.

ANSI escape sequence will work, but you'll have to have the ANSI or
equivalent driver installed. There is a graphics command in MS Fortran 5.0
that will clear the screen in both text and graphics mode.

>C     (Question #3) Is there any same function like SPAWN ?

There is an interface to C library routine in MS Fortran that will do spawn.

There is an interface to C library routine in MS Fortran that will do a shell
escape to DOS.

There are built-in date and time functions in MS Fortran 5.0.

>C     (Question #6) Is there the same intrinsic function INDEX ?

No sure about this one.

>C     (Question #7) How can I put together two character variables ?

There are a few ways to do it. Better to pick a way that's independent of
the compiler you use. One way is to write two strings to a single string
variable, instead of to device 6.

The very first thing to do is to build your own library. Then you can
start talking about compile and link.

It depends on several things, like single and double precision, 2-byte
or 4-byte integer arrays, etc. Best to go by trial and error.

One first piece of advice:

Do NOT pirate software! Buy it and get your own manuals! And if you really
like pirating, don't advertise it on the net and tell the world that you
are pirating software.
